The support for the GT-7200 comes either from the Plustek backend,
or from the modified EPSON backend that is provided by IScan. When you
installed only those parts of IScan that compiled, you did replace
the original EPSON backend from the Sane distribution. Support for
the Perfection 1250 and 1260 in the IScan version of the EPSON=20
backend is what got EPSON KOWA in trouble with the GPL. They provide
a binary library that adds support for these two scanners that is
linked into the backend.=20

Is it a compile error or a link error? The package also contains another
binary library that provides the image manipulation routines from=20
EPSON's Mac and Windows drivers. This is a C++ library and therefore
requires you to use the same compiler as was used to create this library.
That is, up until GCC 3.2. From here on, it should no longer matter (once
EPSON KOWA delivers a library that was compiled with GCC 3.2).

The backend provided with IScan is a regular Sane backend, it can=20
therefore work with all Sane frontends.=20
Have you tried the RPM package of IScan? This should get you
around the compile/link problem.
